◆         EPC-based rebuild for reheating furnaces

CISDI is to apply multiple energy-conserving and intelligent technologies and equipment for green rebuilds at Pangang Metalwork Co.

Reheating furnaces for a high-speed wire-rod rolling line and a high-speed bar rolling line will be rebuilt to operate online.

Part of the Pangang Group, the metalwork company is based in Panzhihua City in China’s Sichuan Province.

It requires the wire-rod rolling line’s furnace to achieve an hourly output of 130 tonnes. The furnace serving the bar-rolling line will meet a 170-tonne target.

◆         EPC-based services for colour coating line

A new colour coating line will be built for Chengdu Plate Co.’s sheet metal production. Its product is used for high-end home appliances.

CISDI’s main tech focuses on curing furnace hot air circulating and RTO waste gas burning systems. It will transform the existing galvanised and galvaluminised sheets to coated products, which have a higher added value.

Chengdu Plate Co. is part of the Pangang Group. The 80,000t/a colour coating line will expand Pangang’s product range and improve its market competitiveness and economic returns.

◆         EPC-based upgrade for reheating furnace 3

Reheating furnace 3 at Xichang Steel’s 2,050mm hot strip rolling line under Pangang Group will be upgraded by CISDI to an EPC mode.

It’s the first of the line’s three reheating furnaces to be upgraded.

CISDI tech will enable full-process automatic tracking, smart combustion model control and one-touch combustion operation.

The upgrade will play a key part in enhancing the line’s quality and production capacity.

The CISDI-supplied reheating furnace 4 for the same line went into operation in June 2019 and has been highly successful.

A Pangang spokesperson commented: “‘The new furnace has been performing to China’s top levels, thanks to CISDI’s efficient, energy-saving combustion system, advanced automation control for furnace intelligent combustion and its reliable machinery.”

Pangang 

China’s first independently-designed and built large steel complex, Panang has become renowned for its ivory, sculpted profile.

Chongqing Ferrous Metallurgy Design Institute (the predecessor of CISDI, which operated from 1958 to 1978) designed the world’s first large vanadium-titanium smelting blast furnace for Pangang and became China’s first design institute able to independently undertake the engineering of a large steel complex.

CISDI has forged a lasting partnership with Pangang and continues to provide services for its full process, from ironmaking to steelmaking, continuous casting and cold rolling.
